| In West Henan, there is a poly-metal mineral centralization of Xiongershan, which contains gold and silver. At the aspect of tectonics, it is just at the joint terrain of the south edge of North China Croton and Qingling orogen. The finding of Lizigou gold deposit is the new achievement which is prospected by No.2 Geological Team of Nonferrous Geology and Mining Bureau.In the deposit, there are more than 30 tectonics alteration zones containing gold,which suggests the super prospecting potential.Based on the analysis of the results of the other geologists, the effective field geological survey has been done,such as systematically analyzing the characteristics of strata, structure,magma, geophysics, geo-chemistry and so on.And following geological rules have been concluded:1,the gold ore-body presented lamellose shape,and which is controlled by the tectonic zone; 2,the gold mineralization is closely related to silication and pyritezation. According to the feature of minerals associations and the relationship of ore-veins intruding, the metollogenic processes have been divided into 3 periods:quartz-pyrite period, quartz-poly-metal sulfides periods and quartzes-carbonate period.Through the analyzing the metallogenic factors, such as lithology, structure and magatite, it is concluded that the following prospection should emphasize on the rules of tectonics and metallogenics, especially analysis on the tectonic zones of faults and regional NE-trending faults.Based on analysis of the rules of the metallogenic richment, some geological rules have been concluded, the rich gold mineralization occurred on the places where ore-bodies enlarged, and the mineralization has the trend of "upper poorer but lower richer".Based on the deeply discussed the geological features, metalloginic factors and genesis, the prospecting clues of gold mineralization have been carried out, and the prospecting direction has been pointed out. And through the geochemical survey,3 prediction targets have been concluded.
